Ageing World Population

The ageing futureSince 1950, the world’s population has almost tripled. All of us are living longer than any generation in human history In the year 2000 there were 100,000 people around the planet who were 100 years old or more. Yet, when they were born, before aeroplanes and antibiotics and atom bombs, before cars and computers, there were very few centenarians anywhere in the world. Now millions of people will live into their 70s, 80s, and 90s, and centenarians will no longer be rare. Advances in medicine and public sanitation mean that infectious diseases no longer kill millions of children and aldults as they did in the past. Healthier food and better health care have made stronger, fitter bodies. Average life expectancy has gone up by 25 years and more in many parts of the world. At the same time the contraceptive pill has had a huge impact on world population levels since the 1970s. Women are having fewer babies and more people are living longer, so the balance between the number of young and old people in the population is changing dramatically. According to the OECD, over next 25 years the number of persioners will rise by 70 milion, while the working age population will rise by only 5 million. But this is good news rather than bad. To be old is not to be ill. Studies have shown that healthy food and regular physical exercise keep mind and body young, and that it’s never too late to start getting fit or learning new things. At 72 the remarkable Helen Klein successfully completed the first Eco – Challenge, a 480 kilometre desert adventure race with swimming, canoeing, white-water rafting, running, horse-riding, and rock climbing. Many older people are active, productive, and useful. Freer than they have ever been, they are not retired from life but actively part of it. There will be millions more like them in the future, as the most privileged generations that have ever lived find they,too,grow old.

...Ageingpopulation –any resolutions?
According to the World Health Organization , a country or a city is defined as an ageing society if the number of elders who aged 65 or above exceed 7% of the whole population. With 14% of elders in population, the country would be considered as an aged society. Worse still, if the amount of elders still keep on increasing and reach 20% of the population, the country would be classified as an hyper-aged society. Recently, the ageingpopulation has been under the spotlight all over the world. This worldwide issue has aroused public concern and surely Hong Kong is not an exception. According to the Hong Kong Population Projections published in July, 2012, there are in total 13% of elders who aged 65 or over in our population, which means that Hong Kong is going to transform into an aged society. What’s more, it is predicted that we would turn into hyper-aged society in 2026, with 23% of elderly people in population.
Such shocking data actually did a good warning effect , which successfully remind government to take long term measures at once to tackle the problem. Or not, ageingpopulation would lower Hong Kong’s labour force, which would then affect Hong Kong’s productivity and hence our competitiveness in the world...

...can do is to prepare for the bad times and enjoy the good times.
In the present day world the crisis of food in the whole world has become a burning problem. Gambia, Indonesia and Philippines are sacrificing food crisis. Food is the foundation of human live and people cannot survive without it. Food security is a vital issue facing the other countries around the world. However, food shortage is becoming increasingly severe in this day and age. There are several reasons which led to the universal food shortage and they are interconnected to each other. Increasing worldpopulation, extreme weather and the wide spread use of biofuels are the main causes of worldwide shortage of food.

...biological factors that affect evolution. In EvolutionLab, two populations of finches are tracked over the course of 300 years on two different islands to see how changing the traits of the birds and their environment affect their long term viability as a sustainable population. Let’s begin by doing a “null experiment” where conditions are identical on the two islands.
Set the “revisit in” drop-down menu to 300 years and then click the Run Experiment button. Click the Input Summary tab and note that in this experiment and note that all factors (both biological and ecological) were identical. Then click the Beak Size tab. Which of the following is true? (Keep in mind that the term “rate” refers to how fast, not how much. Also, we are looking for major differences, not minor ones due to random chance.)
a. When all factors are equal, the beak size of both species increased at a different rate over 300 years.
b. When all factors are equal, the beak size of both species increased at roughly the same rate over 300 years.
2. Click the Population tab. Which of the following is true?
a. The finch populations of both islands increased at roughly the same rate over 300 years.
b. The finch populations of both islands increased at different rates over 300 years
3. Based on the results for beak size and population numbers, what can you conclude about evolution when all factors are equal?...

...Population
I. INTRODUCTION
A population is all the organisms of the same group or species who live in the same geographical area and are capable of interbreeding. In ecology the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is such that inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas. Normally breeding is substantially more common within the area than across the border.
In sociology, population refers to a collection of human beings. Demography is a social science which entails the statistical study of human populations.
II. History
Population growth was not always linear. Famine, war, or disease often decimated local or regional cultures. In fact, as population grew, another pattern of human history emerged - natural and human-induced disasters that killed large numbers of people.
Historically, human numbers were greatly limited by disease. This was especially true as growing populations became more concentrated in cities, where people were more easily exposed to infectious agents. (It takes a minimum population for diseases to sustain themselves. Measles, for example, requires about 7,000 susceptible individuals to assure its survival. A...

...Earth can sustain? And if there is, are we getting close to that number?
It’s a sensitive topic for many people and nations, but the growth of human population may also be the most important topic facing the future of the human race.
Energy consumption and water are major concerns as our population continues to rise.
“The top-three grain producing countries of the planet, India, China are the United States, all have unsustainable pumping for irrigation and water tables are sinking in these countries dramatically. In India, the water table is sinking by about 10 feet a year. And more and more farms are turning to desert as farmers can no longer reach the water, there are about 150 million people in India now being kept alive through unsustainable pumping of underground aquifers. When that water returns out, those people will face immediate starvation.”
“In reality, the problem we have is not climate change, it’s not water shortage, it’s not loss of biodiversity, it’s not degradation of soils. It is overuse of the Earth’s resources by the human endeavor.”
"Continuing growth of the human population is the most serious environmental problem for our planet and for our nation. The consequences of that growth are all around us—loss of open space, air and water pollution, and never-ending sprawl. Habitat loss due to population growth is by far the greatest threat to wildlife. We simply must face up to this...

...issues may be contributed to the major problem of our expanding worldpopulation. According to studies, the worldpopulation will be reaching 7 billion individuals this month. Our knowledge of how to control our increasingly high rate of worldpopulation may hold a significant solution on how these world conflicts may be controlled. If the knowledge and prevention of our expanding population seizes to act, our earthly planet may be in for a long road of unfortunate and threatening consequences. The two articles discussed in this essay address how citizens need to take on the challenge of reducing worldpopulation and what problems may continue to arise if we do not take action on such matter.
First, in Jeffrey Sach's article, he notably states that with the rise of the worldpopulation reaching 7 billion that there are many consequences that must be stabilized in order to avoid major issues for our own humanity. Sachs begins his article with clearly discussing the environmental conflicts that we are and will continue to face with a growing population. Sachs states how the world's agricultural systems are depleting our natural world. Species are becoming extinct with loss of their habitat due to expansion of our industrialized agriculture. As well, greenhouse...

...years, worldpopulation multiplied more rapidly than ever before, and more rapidly than it is projected to grow in the future. In 1950, the world had 2.5 billion people; and in 2005, the world had 6.5 billion people. By 2050, this number could rise to more than 9 billion (see chart "WorldPopulation Growth, 1950-2050").
Anthropologists believe the human species dates back at least 3 million years. For most of our history, these distant ancestors lived a precarious existence as hunters and gatherers. This way of life kept their total numbers small, probably less than 10 million. However, as agriculture was introduced, communities evolved that could support more people.
Worldpopulation expanded to about 300 million by A.D. 1 and continued to grow at a moderate rate. But after the start of the Industrial Revolution in the 18th century, living standards rose and widespread famines and epidemics diminished in some regions. Population growth accelerated. The population climbed to about 760 million in 1750 and reached 1 billion around 1800.

Population Density
Population Density maybe defined as the number of people living per unit of an area (e.g. per square mile); the number of people relative to the space occupied by them.
How to calculate population density:
Divide population by area and round off to the nearest whole number.
